Discretization and convergence of the ballistic Benamou-Brenier formulation of the porous medium and Burgers' equations

We study the discretization, convergence, and numerical implementation of recent reformulations of the quadratic porous medium equation (multidimensional and anisotropic) and Burgers' equation (one-dimensional, with optional viscosity), as forward…

Self-assembly dynamics of simple icosahedral nucleocapsids under high and low capsid protein concentrations

All viruses on Earth depend on host cell machinery for replication, a process that entails a complex self-assembly mechanism. The cowpea chlorotic mottle virus (CCMV) is a simple, icosahedral, non-enveloped, single-stranded RNA (ssRNA) plant virus…

Power spectral analysis of voltage-gated channels in neurons

This article develops a fundamental insight into the behavior of neuronal membranes, focusing on their responses to stimuli measured with power spectra in the frequency domain. It explores the use of linear and nonlinear (quadratic sinusoidal…

Probing single-molecule dynamics in self-assembling viral nucleocapsids

All viruses on Earth rely on host cell machinery for replication, a process that involves a complex self-assembly mechanism. Our aim here is to scrutinize in real time the growth of icosahedral viral nucleocapsids with single-molecule precision…

Effect of real-world perturbations on wave breaking due to a sharp-crested superharmonic instability

The mechanism for the emergence of breaking water waves in deep water, based on the superharmonic instability of periodic Stokes waves, is tested for the effect of real-world perturbations (dissipation, approximation error, changes in depth, nonzero…

Application of Zonal Reduced-Order-Modelling to tire rolling simulation

Physic-based simulation remains a key enabler for real-world ever-growing complex industrial systems especially when crucial decisions are needed. While classical approaches have proven their accuracy and robustness over the years and come with a…

A purely analytic derivation of Bonnet surfaces

Bonnet has characterized his surfaces by a geometric condition. What is done here is a characterization of the same surfaces by two analytic conditions: (i) the mean curvature H of a surface in R^3 should admit a reduction to an ordinary…

The N-link model for slender rods in a viscous fluid: well-posedness and convergence to classical elastohydrodynamics equations

Flexible fibers at the microscopic scale, such as flagella and cilia, play essential roles in biological and synthetic systems. The dynamics of these slender filaments in viscous flows involve intricate interactions between their mechanical…

L1-Norm Redundant Delaunay Phase Unwrapping and Gradient Correction

This article deals with arrays of real numbers which have been reduced modulo 2h into theinterval [−h, h] where h > 0 is a positive real number. Such an array is said to be wrappedmodulo 2h. Often, the elements of these arrays correspond to…
